All sides add up to the perimeter. The perimeter of the kite is 27 units then the correct option is C.
What is the definition of geometry?It is concerned with the geometry, region, and density of various 2D and 3D forms.
The Pythagoras theorem will determine the kite's length (x).
H² = P² + B²
H² = 15² + 8²
H² = 225 + 64
H² = 289
H = 17
Then
[tex]\rm x = \dfrac{H}{2} \\\\x = \dfrac{17}{2}\\\\x = 8.5[/tex]
And another length of the kite is 5 units.
Then the perimeter of the kite will be
Perimeter = 2(8.5 + 5)
Perimeter = 27

Answer:
$24
Step-by-step explanation:
PRICE=$80
DISCOUNT=70٪ OF $80=(70/100)×80=70×80/100=$56
HENCE DISCOUNT=$56
NOW THE PRICE=$80-$56=$24

If you donate $150 in total a year , How much money did you donate on the first month of the year.
Answer:
$12.50
Step-by-step explanation:
You donate $150 in total in a year.
To find out how much you donated on the first month, remember the relation between a year and number of months.
⇒ 1 year = 12 months
⇒ 1 month = 1/12 year
Finding the amount donated
Divide the money donated in a year by 12$150/12$12.50Will V − E + F always equal 2?
The expression V − E + F is an illustration of the Euler's formula.
The expression V − E + F is always 2
How to determine the true statement?The equation is given as:
V - E + F = 2
Where:
V represents the verticesE represents the edgesF represents the facesAccording to the Euler's formula, the relationship between V, E and F is:

Beth and Leslie are trying to decide which one of them gets to portray the lead character in a student play. They will use a random number generator to produce an integer. If the integer that comes up is odd, Beth gets to play the lead, and if the integer is even, Leslie gets to play the lead. Having the random integer generated be in which interval will make this a fair decision?
A) from 2 to 10 B) from 3 to 15 C) from 5 to 20 D) from 5 to 25
The fair interval illustrates a sample space
The interval that will make a fair decision is from 5 to 20
How to determine the fair interval?From the question, we understand that:
Beth plays the lead, and if the integer is even, Leslie plays the lead, if otherwiseSince they choose odd and even integers, then the sample space must be divisible by the number of people (i.e 2 people)
The sample space (S) is calculated as:
S = Highest - Least + 1
A) from 2 to 10S = 10 - 2 + 1 = 9
B) from 3 to 15S = 15 - 3 + 1 = 13
C) from 5 to 20S = 20 - 5 + 1 = 16
D) from 5 to 25S = 25 - 5 + 1 = 21
Only 16 can be divisible by 2
Hence, the interval that will make a fair decision is from 5 to 20

Question 1
The prism shown in the diagram has a volume of 39 units. What is the volume of the pyramid? Explain your reasoning.
Question 2
Consider this cone and pyramid, which have the same height, h. Planes parallel to the base cut through each solid at equal
heights, as shown.
Part A
What is the approximate area of each cross section of the cone and pyramid?
Type the correct answer in each box. Use numerals Instead of words.
Part B
Consider your results from part A. What conclusion can you draw about the volumes of the cone and pyramid? Explain
your reasoning.
Part C
The volume of the pyramid is one-third of the area of its base multiplied by its height, which is 144/3 pi h cubic units. Using
this measurement and your answer from part B, derive a formula for the volume of a cone.
The volume of the cone and pyramid are the same.
Formula for volume of cone = ⅓(144π × h)
What is the Volume of a Triangular Pyramid and a Cone?Volume of cone = ⅓[πr² × height of cone)
Volume of triangular pyramid = ⅓[(½bh × height of pyramid)]
Also note the following:
Area of a circle = πr²
Area of a triangle = ½bh
Part A:
Area of circle 1 = πr² = π(12²) = 144π units²
Area of circle 2 = πr² = π(6²) = 36π units²
Area of circle 3 = πr² = π(3²) = 9π units²
Area of triangle 1 = ½(24)(12π) = 144π units²
Area of triangle 2 = ½(12)(6π) = 36π units²
Area of triangle 3 = ½(6)(3π) = 9π units²
Part B: Based on our results in part A, the volumes of the cone and pyramid, having the same height are the same.
Part C:
Volume of pyramid = ⅓(144π × h)
Using this measurement and our conclusion in part B:
Formula for the Volume of a cone = ⅓(144π × h)

x=13.856
y=8
6)
u=4
v=3.464
Step-by-step explanation:
5)
y=hypothesis * sin(opposing angle)/sin(angle opposite of hypothesis)
y = 16*sin(30)/sin(90)
y=8
x=hypothesis * sin(opposing angle)/sin(angle opposite of hypothesis)
x=16*sin(60)/sin(90)
x=13.856
6)
sinA/(opposite of angle A) = sinB/(opposite side of angle B) = sinC/(opposite of side of angle C)
sin(90)/u= sin(30)/2
u *sin(30) = 2* sin(90)
u *sin(30) = 2
u=2/sin(30)
u=2/0.5
u=4
sin(60)/v= sin(30)/2
v *sin(30) = 2* sin(60)
v *sin(30) = 2 * 0.866
v * sin(30) = 1.73
v = 1.73/sin(30)
v = 3.464

Parallelogram ABCD has the following vertices: A(3,6), B(6,8), C(9,6), and D(6,4). In two ut more complete sentences, explain how you can use the coordinates of the vertices to prove that parallelogram ABCD is a rhombus.
Explanation:
A rhombus is a parallelogram in which the diagonals are mutual perpendicular bisectors. The coordinates of the vertices can be used to show ...
the diagonals bisect each otherthe diagonals are perpendicularWhen both these conditions are met, the quadrilateral is a rhombus.
__
Mutual BisectorsThe diagonals will have the same midpoint (bisect each other) if the sum of the coordinates at the ends of one diagonal is the same as the sum of the end point coordinates of the other diagonal:
A +C = B +D
(3, 6) +(9, 6) = (6, 8) +(6, 4)
(3+9, 6 +6) = (6 +6, 8 +4)
(12, 12) = (12, 12) . . . . . . midpoints are the same; ABCD is a parallelogram
__
PerpendicularThe diagonals will be perpendicular if the sum of the products of the coordinate differences of their end points is zero.
AC⋅BD = (C -A)⋅(D -B) = (9 -3, 6 -6)⋅(6 -6, 4 -8)
= (6, 0)⋅(0, -4) . . . . . end point differences; we want their dot-product
= (6)(0) +(0)(-4) = 0 +0 = 0 . . . . diagonals are perpendicular
_____
Additional comment
The midpoints are computed as (A+C)/2 and (B+D)/2. We have multiplied each of them by 2 to simplify the arithmetic. Our resulting sums of (12, 12) must be divided by 2 to get the actual midpoint of the rhombus: (6, 6).
The notion of "dot product" is a vector notion. Two vectors are perpendicular when their dot product is zero. The dot product is the scalar sum of the products of corresponding coordinates.

They are exempt from income tax and we would get the income tax withheld as $340.
What is tax?
The person does not have another source of income, and there are no exceptions that are claimed by the person.
The withheld tax which is held every week can be calculated as;
Amount of income tax = 30 % of 1,166
Amount of income tax = $339.6
Amount of income tax = $340
Hence, they are exempt from income tax and we would get the income tax withheld as $340.
